As ambiance narratives offers a unique way to combine representations con- cepts and perceptions of the multiple actors involved in the creation process, this paper assumes that their systematic use as a boundary spanning mechanism, may contribute to both creativity in the design and to the overall fit with the expectations of the actors of the ecosystem. The use of ambiance narratives remains to be explained in such a context as the way they are designed, the process by which they are shared, interpreted and used by the different stakeholders in order to span boundaries has not been explored by research. Based on the case study observations and on the theory of boundary objects and boundary discourse, a new development method is pro- posed where innovation involves heterogenic stakeholders.
